Rapid Fabrication of Large-Area Concave Microlens Array on ZnSe

Rapid Fabrication of Large-Area Concave Microlens Array on ZnSe

A rapid and single-step method for the fabrication of a zinc selenide (ZnSe) concave microlens array through the high-speed line-scanning of a femtosecond laser pulse is presented. Approximately 1.1 million microlenses, with minimized volume and high transparency at wavelengths between approximately...
